Upgrade all pidgin machines within windows domain

Hey,

I would like to know if anybody has a script or something to upgrade pidgin on all machines in a windows network. I am running openfire on a centos linux build with 100 users. We are running outdated pidgin which are security risk. I know i can manually go around and upgrade them but was wondering if there was an easier way or somehow able to deploy the upgrade from my pidgin website that i connect to when i set everything up with AD.

wasnt sure if anyone has done it with group policy within AD.

thanks
